This was my first order from Partsgeek.com. The price for some hard-to-find Denso spark plugs was the lowest I could find, even with the modest shipping rate.
The website is clean and sensible, the confirmation was immediate. Within 20 hours of my order, UPS delivered them to my door. The plugs were in clean, unopened boxes and were packed with care and undamaged. First class service from start to finish!
